git diff with line numbers and proper code alignment/indentation

Question

I obtained this code sample from someone else here:

  git diff --color=always | \\
    gawk \'{bare=$0;gsub(\"\\033[[][0-9]*m\",\"\",bare)};\\
      match(ba         


        

Answer 1

It should be a minor typo (most likely) because printf() in awk expects a , after the format specifiers

printf "-%-8s:", left++ line
